The bifilar pancake coil at its resonant frequency

Are you sure about that MH 
Are you saying that eddy currents will not create heat in the highlighted metals?
All will heat,when held near a spinning rotor full of alternating permanent magnets.

You can actually get non-ferrous metals to levitate above an AC electromagnet, so maybe that's the reason the iron plate is used with those metals. You don't want your morning eggs and bacon flying around the kitchen in your aluminum pan!

(just kidding, the levitation effect is probably not strong enough in the ordinary induction hob, but I have seen fancy induction cooktops advertised that are supposed to levitate the aluminum pans while cooking in them too...)

Hi Brad,

I don't know if MileHigh is slightly confused on that or if he just worded it wrong.  But the induction cooker won't work with those metals only because it has a sensor that detects ferrous metals and will not turn on the coil until there is a ferrous metal near the coil.  When several of us were playing with them a few years ago we had to put some ferrous metal near the coil or bypass the sensing circuit in order to turn on the coil.

Have a good day or should I say night in your case.

I too went out and bought an induction cooker,when Naudin was fooling around with them-the so called OU generator.

I can boil water in a stainless steel pot,that a powerful neo magnet will not stick to,and i can also boil water in my copper camping kettle on top of the induction cooker.
Ali pots work just as well.
So there is the three materials MH listed as !will not work! on an induction cook top,but they all work just fine on mine.

I also had no trouble firing up the copper pancake coil during my experiments.

Soooo, apparently not all induction cookers are the same.  Interesting.

Thanks for the new info Brad.

Take care,

Negative current moving backwards is positive current. A negative Henry is the equivalent of one Tesla of magnetic strength. Both have positive values.

The spark gap collapse is infinite, not the spark. The collapsing magnetic field generates a magnet wave that instantly reaches the most distant parts of the Universe in the Macro space and the infinite reaches of the Quantum-sphere. Tesla invented radio, and his saprk gap generator could send a signal that magnetized metal coherer filings at a distance as Marconi discovered. Tesla believed Gravity and Magnetism were twins like Maxwell electricity and light.

Jerry Bayles evolved a "Unified" field theory with gravity as a cosmological constant rather then light as Einstien with his "Special" theory. The gravity wave is immediate and instantaneous, taking no time to travel at all.

The "Black Hole" at the Galaxy's center has no space but it's huge mass is spinning faster then the speed of light. The gravity spins outward spirally like a nautilus shell describing a proportion known as PHI (1.618).  The mass of the "Spiral Galaxy" and the spatial positions of the inner planets of the solar system sit on the spiral loops. Electron shells follow suit.

I taught G.E.D. to kids with no former schooling and got mutilated here for a jug comparison to a capacitor discharge. Shameless insults were directed at me which would have resulted in a physical beating if made to my face. I demand mutual respect.

Threatening physical violence is a wonderful way to get respect if you are a nine year old.  You can't demand respect.  You have to earn it.
